Lasers & Energy Devices: CO₂, RF Microneedling and IPL Made Simple
Not every device is a laser and not every device solves the same problem. This guide sorts technologies by goal instead of brand name.

Start with the treatment goal
Devices differ in how they deliver energy, how deep they work and what tissue they target. Technology selection therefore starts with the problem: scars and texture, vessels, pigmentation, hair, or laxity and skin quality.
The main categories
- Fractional CO₂: relatively strong resurfacing for selected texture and scar concerns.
- RF microneedling: delivers thermal energy through needles at controlled depths for texture, selected laxity and scars.
- IPL: broad-spectrum light rather than one laser wavelength; used for selected pigment and vascular indications.
- Vascular and pigment lasers: different wavelengths target different chromophores depending on the condition.
The device name alone does not tell you whether it is right for you. Indication, settings and operator experience matter much more.
